To all whom it may concern:

Be it known that I, VIo'roR RAISIN, residing at 48 Boulevard Haussmann, Faris, France, have invented a new and useful Apparatus for Exhausting Materials in Distilleries, Sugar Plants, and the like, which are fully set forth in the following specification.

This invention relates to a device for exiausting materials in distilleries, sugar plants and the like.

This apparatus is shown by way of example in the accompanying drawing, in which Figure l is a longitudinal sect-ion of a receptacle. Fig. 1 is a side view of the receptacle showing the rotating means for the blades. Fig. l illustrates two receptacles placed in series. Figs. .1 and 2 are sections of the same apparatus provided with various devices for advancing the material. Fig. 3 is a section of the apparatus with a feed device constituted by a hydraulic conveyer. Fig. 4 is a longitudinal section of a modified construction of the apparatus.

The receptacle shown in Fig. 1 or each of the receptacles, is divided by means of transverse partitions a, into compartments 6, communicating with each other at the bottom, the number of the compartments varying in accordance with the materials to be treated.

In each of the compartments 6 moves a blade 0 intended to advance the material.

The compartment (Z receiving the material, is arranged behind a certain number of decanting compartments Z), and can be provided in certain cases with a system of screens 6 immersed in the liquid, so as to separate foreign bodies or excessively large pieces.

The material gets into the compartment (Z, passes through the screen 6, if there be any, and is seized by the blade 0 adjoining the said compartment, which projects into the next compartment 6 where it is taken by the next blade, and so on, so that all the particles of the material to be exhausted are constantly in contact with the liquid surrounding them, and travel through a liquid, the richness of which is gradually decreasing.

\Vhen the material thus arrives at the end of the receptacles, a hoisting device f raises it out of the receptacle, and at the moment of its escape, it is watered at g with a certain quantity of water or of liquid to be enriched. This liquid may have been previously heated, if necessary.- In a large number of cases a single receptacle will be sufiidirection of traveling of the material, and

arrow 2 the direction of the current of the liquid. The exhaustion is therefore a gradual and a continuous one. The liquid enriched, after having passed through the compartmerit (Z receiving the material, can carry away a certain quantity of it; in that case it is advisable to insure good decanting of this ,tunbid liquid, the residue bemg returned to the mass being treated. To that end, a certain number of compartments Z) are arranged at the back of the compartment d receiving the material to be treated. These compartments which constitute a real continuous decanter, are provided with blades 0 of suitable dimensions, the object of which is to bring back into the compartment d the particles of material carried away by the liquid current. In order to assist this decanting, the blades 0 are made of decreasing dimensions, and they are also given a decreasing speed of rotation.

In certain cases, it is advantageous to replace the blades 0 0 either by an endless canvas M (Fig. 1) on which will settle the material which will thus be carried in the direction opposite to that of the arrival of the current, or by a system of endless chains N (Fig. 2) provided with blades 29 driving the material settling on the bottom of the apparatus.

Fig. 3 shows by way of example a method of feeding by a hydraulic conveyer. The material to be treated, arriving in the conveyer T, falls into a mixing vat A where it is stirred with the rich juices coming from the washer L through m a and discharged by the pump P into the mixing vat A. The mixing of the material with the juice in question can be effected either by means of a propeller or of any other stirring device, or by admitting compressed air, or by the action of a circulating pump, these different means being used separately or jointly. Moreover, at the outlet of the material treated, it is advantageous, for the purpose of insuring maximum exhaustion, to cause the material exhausted to travel on a perforated conveyer, as shown by Way of example, in Fig. i. The said conveyor T, With one or more floors, receives a shower of Water distributed at r so as to carry away any traces of the material to be dissolved that may remain in the Waste. lhe drained off liquid falls on one or more aprons or bands S Which bring it back to the Washer L, and the material escapes at R, drained and completely exhausted.

Claims:

1. A device for exhausting materials of greater density than their solvents in distilleries, sugar Works and other industries comprising a plurality of receptacles placed in series, each of said receptacles being divided in a plurality of compartments communicating With each other at the bottom, means to convey the material in a direction opposite to the direction of flow of the solvent, a receiving compartment provided with grating to receive the material to be exhausted, compartments adjacent to said receiving compartment to decant the liquid, and means Within said compartment to re turn the material remaining after the decantation to the receiving compartment.

2*. A device for exhausting materials of greater density than their solvents in dis tilleries, sugar Works and other industries comprising a plurality of receptacles placed in series, each of said receptacles being divided into a'plurality o1 compartments communicating With each other at the bottom, means to convey the material in a clirection opposite to the direction of the flow of the solvent, a receiving compartment provided With grating to receive the material to be exhausted, compartments adjacent to said receiving compartment to decant the liquid, blades of decreasing dimensions and speed of rotation provided in said last named C0111- partmcnts to return the material remaining after the decantation' to the receiving compartment.
